Answer:
Investigating Hooke’s Law
This is an example of a common experiment used to investigate Hooke’s Law. It should help you understand how to work scientifically.
Aim of the experiment
To investigate how adding mass to a spring affects its extension.
Method
Set up the apparatus as in the diagram
Add a 10 g mass to the holder and record the spring length.
Add another 10 g mass and record the new spring length.
Take away the previous spring length from the new length to calculate the extension (the difference).
Repeat by adding 10 g masses until 100 g is reached.
Answer:
This is how the student should investigate that weather the spring follows hooks law
Explanation:
Should measure the spring without the weight. Then the student should add the weight to the spring. And measure it again and check the force and the measuring. The student should check the mass, force and distance and add to a graph. therefore the applied force is directly proportional to extension. Check if that follows the hooks law
